Bpeomcation of Letters Patent. Patented Jan. 13, 1920. I

Application filed March 27, 1919. Serial N0. 285,863.

: To all whom it may concern:

Be it known that. I, HUou H. Donna, a

citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New "York, have invented a newand Improved Signal and (iuide Light, of which t 1e fol lowing is a full, clear, and exact description.

This invention relates to signal lights and has for an object the provision of an improved construction which may be used with any form. of lamp now in common use to present an illumination for the locatlon of an object, or as a signal to indicate certain facts.

Another object in view is to, provide a hood and attachment for an electric lamp for indicating numbers or other configurations when in one position and act as an illuminating devicewvlien in a second position.

A further object of the invention, more specifically, is the provision of a hood arranged with numbers or other configurations 'on the exterior part and with a cone shaped central member for distributing the light from the lamp associated with the hood so that part will illuminate thefigures and part will be projected through the cone shaped member for illumination purposes.

In the accompanying drawing:

Figure 1 is a side view of a device embodying the invention, the same, being shown fixed to a lamp.

Fig. 2 is a sectional view through Fig, 1 on line 22, the same being on an enlarged scale. 1 t

Fig. 3 is a sectional view through Fig.2 on line 3-3.

Referring to the accompanying drawing by numerals, 1 indicates an ordinary electric lamp to which the hood 2 is to be applied, as indicated in Fig; 1, the connection consisting of a band. 3 aving upstanding ears through which the clamping bolt 4 passes. The upper edge of the band 3 is soldered or otherwiserigidly secured to the base 5 of hub 2, but there is sufficient resiliency in the metal to allow the metal to be drawn in reasonably tight to grip the upper end of the lam so as to lock the hood firmly thereto. The ase 5 is provided with an aperture 6 through which the light projects into the hood and is divided so that some light goes through the cone shaped deflector 7 and the remaining light is distributed within the hood to illuminate the same in order that the configurations 8 will stand out prominently. Preferably the sheets 9 carrying the numbers or other configurations 8 are transparent and the numbers or other configurations '8 are opaque, though if desired this could be reversed without departing from the spirit of the invention.

lhe various members or plates 9 are held in position insuitable slide-ways provided by the frame 10, which are preferably made from sheet metal, and by retaining strips 11. In forming the frame 10 the corners are bent as shown in Fig. 3, so that the plates 9 will be set back and thereby cause an easier operation of the device, as it may be held in. position to be seen from any point with less chance of mistake. A suitable top 13 is provided for the frame 10, said top having a tubular member 7 soldered or otherwise rigidly secured thereto so as to preferably project a short distancetherebeyond. This member is tapered in order to give the desired illumination 1n axial alinement with the lamp without unnecessarily cuttingoff the proper illumination of the plates'9.

In forming the hood preferably the upper.

part is connected to the base 5 through the use of pins 14 secured to the frame 10 and positioned to extend through the apertures in the upstanding flange or web 15 rigidly secured to base 5. Preferably, there are one or more pins 14. in one side and a catch 16 on the opposite side which is rigidly secured to the band 3 and resiliently acts to hold the engagin end in proper position. The engaging en of the catch passes through a suitable aperture" in the upstanding flange 15 and through a suitable aperture in the frame 10.

In use the device may be used in a large number of different ways, for signaling purposes and also as a trouble lamp. However, it is especially designed to be used in auditoriums, as for instance moving picture shows whereby an usher may signal from near the front of the auditorium the number of vacant seats by turning the proper number to face the rear of the auditorium, while at another time he may point the tapering tubular member 7 toward the vacant seat 'for illuminating the same when a person is about .to be seated. The lamp 1 may, of course, be turned on or off at any time as it is an ordinary electric hand lamp now in common use so that the hood may be used either as a signal or as a trouble lamp at any time, and when not in use will be dark so as not to be seen.

What I claim is: 1 H 1. The combination With a portable lamp,

I of a hood removably secured on the end of the lamp, said hood having signals in its sides, a cone secured in the hood and projecting beyond the outer end of the hood,

said cone causing a division ofthe light so that a portion thereof shines through the cone, and a portion is directed to lllumijecting members between the signals, and a cone secured in the hood and causmg a d1v1- sion of the light, so that a portion thereof shines through the cone, and a portion is directed to illuminate the signals,

3. The combination with a portable, cylindrical, electric lamp, of a rectangular hood, a clamp on the hood removably engaging the lamp, signals in the sides of the vhood, corner brackets'on the hood projecting radially therefrom, said hood having an outer end with a central openlng therein, and a cone secured in said opening and causing a division of the light, so that a portion portion is directed to illuminate the signals.
